Connecting the spa pack to the mains:
The spa power cable (not supplied) must be HO7RN-F type.
Pull the 230 V + earth cable into the electrical panel through the cable gland located on the left hand side
of the electrical panel. The cross section of this cable should be sized for all the spa equipment (refer to
the table on the next page), and protected upstream by a 30 mA RCD (French electrical safety standard
C15-100).
Connect the power cable: the earth to the aluminium terminal strip located on the outside of the panel,
neutral to the N terminal and live to the L1 terminal (under N) of the light grey terminal block located in the
panel.

Dirty or incorrectly tightened connections could create short
circuits and damage the electrical panel, or even start a fire.
Protect the spa power line against over currents and short circuits with a thermal magnetic circuit breaker
located at the head of the spa power line. The thermal magnetic circuit breaker can also act as a circuit
breaker to allow intervention on the electrical components.
